Kalanchoe plant named ‘Kasinyetu’

ABSTRACT

A new and distinct cultivar of  Kalanchoe  plant named ‘Kasinyetu’, characterized by its compact, broadly upright and uniformly mounded plant habit; moderately vigorous growth habit; dark green-colored leaves; uniform and freely flowering habit; bright yellow-colored flowers; and excellent postproduction longevity.

Botanical designation: Kalanchoe blossfeldiana.

Cultivar denomination: ‘KASINYETU’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Kalanchoe plant, botanically known as Kalanchoe blossfeldiana and hereinafter referred to by the name ‘Kasinyetu’.

The new Kalanchoe plant is a product of a planned breeding program conducted by the Inventor in Naaldwijk, The Netherlands. The objective of the breeding program is to create new uniform Kalanchoe plants with attractive leaf and flower coloration.

The new Kalanchoe plant originated from a cross-pollination made by the Inventor in Naaldwijk, The Netherlands in January, 2001, of a proprietary selection of Kalanchoe blossfeldiana identified as code number 20011160-003, not patented, as the female, or seed parent with a proprietary selection of Kalanchoe blossfeldiana identified as code number 20011157-002, not patented, as the male, or pollen, parent. The new Kalanchoe plant was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Naaldwijk, The Netherlands in January, 2002.

Asexual reproduction of the new Kalanchoe plant by vegetative terminal cuttings in a controlled greenhouse environment in Naaldwijk, The Netherlands since October, 2009 has shown that the unique features of this new Kalanchoe plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Kalanchoe have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylength and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Kasinyetu’. These characteristics in combination distinguish ‘Kasinyetu’ as a new and distinct Kalanchoe plant:

-   -   1. Compact, broadly upright and uniformly mounded plant habit.     -   2. Moderately vigorous growth habit.     -   3. Dark green-colored leaves.     -   4. Uniform and freely flowering habit.     -   5. Bright yellow-colored flowers.     -   6. Excellent postproduction longevity.

Plants of the new Kalanchoe can be compared to plants of the female parent selection. Plants of the new Kalanchoe differ primarily from plants of the female parent selection in plant habit as plants of the new Kalanchoe are more uniform than plants of the female parent selection.

Plants of the new Kalanchoe can be compared to plants of the male parent selection. Plants of the new Kalanchoe differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Kalanchoe are more freely flowering than         plants of the male parent selection.     -   2. Plants of the new Kalanchoe have larger flowers than plants         of the male parent selection.

Plants of the new Kalanchoe can be compared to plants of the Kalanchoe blossfeldiana ‘Kasipi’, disclosed in U.S. Plant patent application Ser. No. 13/815,470. In side-by-side comparisons conducted in Naaldwijk, The Netherlands, plants of the new Kalanchoe differed primarily from plants of ‘Kasipi’ in the following characteristics:

-   -   1. Plants of the new Kalanchoe were more compact than plants of         ‘Kasipi’.     -   2. Plants of the new Kalanchoe and ‘Kasipi’ differed in leaf         shape.     -   3. Plants of the new Kalanchoe had smaller flowers with shorter         flower petals than plants of ‘Kasipi’.     -   4. Plants of the new Kalanchoe and ‘Kasipi’ differed in flower         color as plants of ‘Kasipi’ had bright red purple-colored         flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Kalanchoe plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Kalanchoe plant.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Kasinyetu’ grown in a container.

The photograph on the second sheet are close-up views of the upper and lower surfaces of typical flowers (top), a typical inflorescence (center) and the upper and lower surfaces of typical leaves (bottom).

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the spring in 12-cm containers in a glass-covered greenhouse in Naaldwijk, The Netherlands and under cultural practices typical of commercial Kalanchoe production. During the production of the plants, day temperatures ranged from 20° C. to 30° C., night temperatures ranged from 18° C. to 25° C. and light levels ranged from 5 to 60 kilolux. Plants received long day/short night conditions (more than 14 hours of light) for about four weeks; plants then received photoinductive short day/long night conditions (minimum 14 hours darkness) until flowering. Plants were 13 weeks old when the photographs and the description were taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
